This invention" relateslto a floor treating particularly to a floor polish- I apparatus, and ingmachine a J Y The general object'of -the nvention 1s: to provide a new and lmprovedfloor treating machine which-will besimple in constructionand eflicient in operation and particularly to'provide a floor polishing machine haying'la motor, driven "brush mounted within i lea-housing Y i 1 Among the characteristic features of the invention area housinghavinga body formed bybending a [sheet of metal" intothe desired shape; "an improved arrangement wherebya '15"p(")wer11; operated: floor pohshing brush mounted'withinthe housing ;;'a yleld'lng base; 3 v p suitably fastened to the body plate 9S0 as'to completely enclose the mechanism within'the housing. As is apparent the motor is supa such as a pad of lambskin or thej lik'eg'for the" housing and which alsofserves-as a; p015.

' Other objects and advantages will appear from vthe following detailed description,

taken in connection with the accompanying drawings, in which i p i Fig; 1 is a top plan'view of a floor treating machine, constructed in accordance wlth the invention parts, being broken away to lllus trate the interior structure of the machine;

Fig. 2-is an end elevation partly broken away; i

V of the machine a Fig. 3 1s an end elevation of amodification, and v e 4 Fig. 4: is a partial plan-view of the mach ne showing the handle hinged on the casing.

' a In a preferred embodiment of the invention illustrated in Figs. 1 and-20f the drawings, a motor 2 for-driving the polishing brush 16 is inou'ntedwithina housing 1. body 9 of this housingis formedby shaping o-rbending a flat sheet of metal into the dei do hapek A metal plateis shaped so that it closelv conforms to the/contour of the V motor 2, this end ofstheplate being fastenedby a bolt '3 or other suitable fastening means to the casing of the motor. There isfthus prorided' a, compactarrangement of shell and motor which, can be readil a s le simply sliding the motor endwise into the 1 shell, This construction also permits'the motor end the-plate inclines upwardlyas at4 andis then bent'downwardly to form the body 9'of the housing indicated by the ref- 'erencenumeral 1, The extreme forward portionof the plate maybe bent into concavo-'=,' convex form soas to provide a receptacle 6, V which'is adapted to receive the polishing medium asjwill-be hereinafter explained.

Side plates 7 -pr'ovided with openings 8.are'

portedby the casing and is enclosed on all sides by the surrounding plate 9 and the plates 7 A" plurality of vanes 10 are preferably mounted on the ends of .the motorshaft 11 so that in operation a current of air is forced out through the openings 8 in the side plates 7 at" each end of "the motor, thus preventing" dirt and other foreign matter from entering the motor structure and providing proper 'ventilat ionfo'r said motor;

-.Pulleys 12 fastened onfeachend of the moa: j, 'tor. shaft are' provided withbelt s 13 which are'in driving connection with'pulleysl l I keyed to shaft 15 on which-the; polishing brush 16 having bristles of suitable thickness is mounted jhTlle shaft 15 is rotatablymounted in radial arms 17 which in turn are piv- 'otallymounted on the hub po'rtion's of casing main arms so as'to provide a rigid-frame construction, if the radial arms are adjusted so that they, pivot loosely on the hub portions 'the 'po'lishing pressure of the brushis equivalent to the weight of 'the"bru'sh; However 5 I 'whentlie clamping device shown 341319 is tight-J e z s t; the ,ml a rm c nn t ew ng on shaft 1111" the polishing pressure -of; brush 29'. Across bar;18 mayfextend between the f skilled in the art and this invention is there fore not to be limited to the structure dispad and thence onto the floor surface.

16 is equivalent to the weight of the entire machine.

If desired the radial arms may be rigidly fastened to the motor casing 29 thus providing a simple construction wherein the polishing pressure of the brush is always equivalent to the weight of the entire machine. lVith this construction, instead of having the pulleys 14 mounted on the brush shaft 15 these pulleys may be fastened to or formed integral with the brush core 20, this core'being mounted in oiless bearings carried by the radial arms. These arms would be located between the upper and lower runs of the driving belt so that they would not interfere with the brush drive. V

Pads 21, 22 of lambskin or other suitable material are placed on the casing beneath the motor and the receptacle 6. These pads resiliently support the mechanism described and also serve as a polishing means when moved over the floor surface. The receptacle 6 is provided with openings 23 through which the polishing medium is distributed onto the Thus the pad 22 serves to apply the polishing medium to the floor surface and also polish this floor surface. I

A handle 24 provided with a cable cord 25 adapted to supply the electrical energy to the motor, is pivotally mounted on the housing at 26. This pivotal mounting is poabove the surface of the floor by the brush 16. A bumper 28 of rubber or other suitable material is fastened to the front and sides.

It will, of course, be understood, that while a specific embodiment of the invention has been shown and described, various changes in the details thereof may be made by those closed but only by the scope of the appended claims.

What is claimed is: 1. A floor treating machine comprising a brush, a motor for driving the brush, a housing for the brush, said housing'having a body I formed by bending'a flat sheet of metal into the desired shape, one end of said body conforming to the contour of thefmotor and resilient means for supporting said housing.

2.. Afloor treating machine comprising a brush, a motor for driving the brush, a housing for the brush, said housing having a body formed by bending a flat sheet of metal into the desired shape, one end of said body conforming to the contour of the motor, the other end bent to form a receptacle, and pads on the opposite ends of said housing to support said housing.

3. In a floor treating machine, a brush, a motor for driving the brush, a housing enclosingthe brush and motor, a support for the motor, a polishing material applicator mounted on said housing in front of the brush, and a polishing pad mounted upon said housing, said applicator and housing supporting the entire machine upon the floor.

i. In a floor treating machine, a brush, a motor for driving-the brush, a cylindrical housing for the motor having a projecting portion providing a hood for said br ush,zand

polishing pads mounted upon the brush hood and motor housing for supportingthe machine upon the fioor. I

5. In a floor treating machine, ,a brush, 'a motor for driving the brush, a housing for the motor, a polishing material applicator mounted forward of the brush, and a polishmg pad mountedupon the motor housing behind the brush.

6. In a floor treating machine, amotor, a

framejpivoted on said motor, a brush journailed in said frame,driving connectionsbetween said motor and said brush, .a housing mounted upon said motor and extending over said brush, .and a polishing material applicator mounted upon .said housing forwardly of said brush and serving to at least partially support said machine upon the floor.

In witness whereof, I hereunto subscribe my name this 14th day of March,.1927. I
